They have a top and a bottom as well as an oral side (including a mouth) and an aboral side (without a mouth). In the course of evolution, these segments evolved to become specialized cells and organs. As forward motion is used to travel, this means an animals head meets and reacts to stimuli before the rest of the body. Bilateral symmetry allows for the animal to have directed movement, which can help when searching for food or escaping predators. Repetition is the use of similar elements in a design, which can be used to create rhythm or consistency.

"Radial vs. 1 What are the advantages of bilateral symmetry and Cephalization? Symmetry is also beneficial in terms of balance, and is important for forward-propelling movement in a specific direction as well as making the process of movement easier; for example, if a human had one leg longer than the other, they would be unable to walk or run effectively in the face of danger, so this is a trait which has stuck as being advantageous through evolution. These are classified as being asymmetrical.

As well as having a symmetrical body shape, the patterns on their wings are almost identical. Lastly, white space is the empty or negative space around or between the elements in a design, which can be used to create clarity or focus. Pentaradial has five sections, which are all equal, such as in sea urchins and sand dollars. The bilateral body plan may also be advantageous because it permits organisms to be more streamline. Deuterostomes Characteristics & Examples | What is a Deuterostome? Bilateral symmetry, or mirror symmetry, mirrors images along a central axis.
